Disklavier

Bill
You are correct that you can not just copy .fil or midi files to a CD and  
play them on a Disklavier.
 
The CD player will only play .wav files with a midi encoded audio channel.  
IE Yamaha PianoSoft Audio CD's or Commercial CD's that sync with Yamaha  
PainoSoft Smart disks. 
 
A floppy disk will hold 70 - 100 songs so it is no big deal to use a  floppy.
 
You can use the MID2PianoCD program to create CD's that  will play on the CD 
drive. However the ,wav files are so big you can only put  10-20 songs on a CD.
